The approximations are applied to one-speed neutron transport equation with forward and backward scattering. Analytical diffusion length equations are obtained and the numerical results obtained from modified U1 and P1 approximations for different collision parameters (c) are compared with each other.}, number={1}, publisher={Osmaniye Korkut Ata Üniversitesi}
